High-Precision Inflatek Valve for Powder Containment and Dosing

The Inflatek valve, also known as an inflatable seal valve, is a reference industrial solution for the precise control of powder and bulk material flow. Designed for industries such as energy, food processing, chemicals, minerals, and construction, it features an inflatable sealing system that ensures optimal tightness and a leak-free closure. Unlike conventional valves, the Inflatek valve guarantees full containment of the processed materials, thereby reducing the risk of contamination and dust emission.

Its robust build and long-lasting performance make it a strategic choice for manufacturers aiming to optimise their processes while meeting safety and environmental standards. This article provides an in-depth overview of the features, advantages, and applications of the Inflatek valve, highlighting essential criteria for successful implementation in your facility.

1.1 Definition and Operating Principle

The Inflatek valve is an innovative solution for regulating the flow of powders and bulk solids, designed to offer superior sealing and minimise product loss. Unlike traditional valves, it includes a mobile cap that, when engaged by an inflatable seal, applies even pressure to the flow channel, ensuring a hermetic, leak-free seal.

Its high-performance inflatable seal system removes excessive contact points, reducing mechanical wear and extending service life. This design also offers easier handling and simplified maintenance, ideal for demanding process environments.

1.2 Key Components of the Inflatek Valve

• Valve body: constructed from stainless steel for excellent resistance to corrosion and abrasion in harsh settings.
• Mobile cap: a crucial part ensuring secure closure and effective product containment.
• Inflatable seal: engineered for precise inflation/deflation to achieve a perfect seal while protecting product integrity.
• Pneumatic actuator: allows for automated, accurate opening and closing, reducing manual intervention and improving reliability.

1.3 Why Choose an Inflatek Valve?

• Outstanding sealing: eliminates leakage for a safe and hygienic process environment.
• Extended durability: robust construction with high-quality materials ensures a long service life.

• FDA and CE compliant for applications in the food and pharmaceutical sectors.
• Meets UK and EU environmental regulations, helping to prevent pollution and ensure workplace safety.

The Inflatek valve is a key piece of equipment for ensuring safe and efficient control of powder and bulk material flow. With its high sealing performance, durability, and adaptability, it is a strategic investment for industries looking to optimise production and minimise losses.

5.1 What is the typical service life of an Inflatek valve?

A well-maintained Inflatek valve can last many years due to its robust design and durable inflatable seal, which reduces wear. The lifespan will vary depending on material quality and usage frequency. Preventive maintenance helps maximise longevity.

5.2 Is the Inflatek valve suitable for all types of powders?

Yes, the Inflatek valve is designed for a wide variety of powders, including:

• Fine powders: such as flour, sugar, talc.
• Abrasive materials: like sand, cement, or metallic oxides.
• Hygroscopic substances: such as salts, acids, or moisture-sensitive chemicals.
• Toxic and explosive powders: with dedicated designs for high-risk applications.

Material and configuration choices depend on the specific characteristics of the powder in question.

5.3 Can the Inflatek valve be used in ATEX zones?

Yes, several Inflatek valve models are ATEX certified (zones 20, 21, 22), suitable for use in explosive atmospheres. These models are built with specialised materials and spark-resistant components to meet strict UK and EU safety regulations.

5.4 How to maintain an Inflatek valve to extend its lifespan?

Routine maintenance is crucial for keeping the Inflatek valve operating at peak performance. Recommendations include:

• Regular inspection of the inflatable seal for early wear signs.
• Frequent cleaning of the mobile cap and product passage to prevent buildup or blockage.
• Monitoring actuators and sensors to ensure proper system response.
• Preventive replacement of worn components to avoid unexpected downtime.

The Inflatek valve is the ideal solution to ensure precise dosing and effective sealing in powder-handling operations.
